Abstract:

Objective   To analyze the influncing factors and interaction mechanisms of acquired immune deficiency syndrome(AIDS) high risk behavior among female sex workers(FSWs) based on the information-motivation-behavioral skills(IMB)model. Methods    Participants (n=328) were recruited using respondentdriven sampling method. A self-administered questionnaire was used to collect the data. Structural equation modeling was used to assess the IMB model. Results   The fitting evaluation index of the IMB model was accepted. Prevention information and motivation worked through behavioral skills to influence prevention behaviors. Motivation had direct and indirect effects of statistical significance on the prevention behaviors(P＜0.05). Behavioral skills had more effects on prevention behaviors than motivation. Conclusion   Behavioral skills had the most effects on prevention behaviors and also acted as a metavariable to regulate the effects of prevention information and motivation on prevention behaviors.
